Applicability: All Model Mystere Falcon 900 series airplanes, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To prevent breakage of mechanical elements of the thrust reverser door actuating system, accomplish the following:

A. Within 60 days after the effective date of this AD, modify the thrust reverser automatic stowage electrical control system and ensure the segregation, at the ground/flight proximity detector level, of the braking and thrust reverser control circuits, in accordance with the procedures in AMD-BA Service Bulletin F900-54, Revision 1, dated July 19, 1989, or Revision 2, dated September 20, 1989.

B. In accordance with the following schedule, identify the source of the end fittings of the thrust reverser door actuating rods and reinforce the thrust reverser actuating mechanism (actuating rods and hinge pin) in accordance with AMD-BA Service Bulletin F900-61, dated July 19, 1989 (Reference Hurel-DuBois Service Bulletin F900HD001):

1. Prior to the accumulation of 800 landings since the airplane was new on airplanes equipped with end fittings manufactured by Frankenjura, or within 60 days after the effective date of this AD, whichever occurs later, or

2. Prior to the accumulation of 1,300 landings since the airplane was new on airplanes equipped with end fittings manufactured by Sarma, or within 60 days after the effective date of this AD, whichever occurs later.

C. If the reinforcement procedure required by paragraph B., above, is accomplished after the accumulation of 800 landings on airplanes equipped with Frankenjura end fittings, or after the accumulation of 1,300 landings on airplanes equipped with Sarma end fittings, then repair the synchronizing bell crank hinge fitting within 60 days after the effective date of this AD, in accordance with AMD-BA Service Bulletin F900-61, dated July 19, 1989. (This service bulletin references Hurel-DuBois Service Bulletin F900HD001.)

D. Prior to the accumulation of 4,000 landings, or within 60 days after the effective date of this AD, whichever occurs later, modify the hydraulic actuator Part Number (P/N) 106124 to P/N 106124- 01 by replacing end-fitting P/N 106124200101 with a new end-fitting P/N 106124200102, in accordance with the manufacturer's maintenance manual, Maintenance Procedure 78-305.

E. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM- 113, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment and then send it to the Manager, Standardization Branch, ANM-113.

F. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Falcon Jet Corporation, Customer Support Department, Teterboro Airport, Teterboro, New Jersey 07608. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 17900 Pacific Highway South, Seattle, Washington, or the Standardization Branch, 9010 East Marginal Way South, Seattle, Washington.

Airworthiness Directive 90-03-07 R1 revises AD 90-03-07, Amendment 39-6485.

The effective date of the requirements of Amendment 39-6575 (AD 90-03-07 R1) remains February 26, 1990, as specified in Amendment 39-6485.
